Abstract

A light for a curing instrument includes a plurality of light sources, each producing an incident light beam. The incident light beams are combined to produce a single output beam, which exhibits a broader spectral width than any of the incident light beams. In one embodiment of the invention, the output beam exhibits an intensity over a spectral range defined by a first characteristic wavelength of a first of the plurality of light sources and a second characteristic wavelength of a second of the plurality of lights sources such that the intensity varies by no more than 25 percent over the range. In another embodiment of the invention including a one or more blue LED light sources among the plurality of light sources, at least one white LED is included in the plurality of light sources in order to generate an output light beam having a component portion that is characterized as green. In a third embodiment of the invention, a plurality of fiber optic bundles receive the incident light beams, and are arranged at a transmitting end so that individual fibers from the plurality of bundles are randomly combined to form a single output surface for transmitting the output beam. <IMAGE>
